Taxonomic review of the family Tiphiidae (Hymenoptera: Vespoidea) in South Korea.

Abstract: Twenty South Korean tiphiid species are taxonomically reviewed. Among them, Tiphia burrelli is new to Korea. Based on the observation of the holotype, Tiphia seoulensis Tsuneki 1986 is synomymized with T. rufomandibulata Smith 1873. Male of T. koreana hitherto unknown is newly described. Revised key to species, recognizable characters and digital images are provided. Genital structures of several species hitherto unknown are also given.

Hospicidal behavior of the cleptoparasitic wasp Sapyga luteomaculata and investigation into ontogenetic changes in its larval anatomy (Hymenoptera, Vespoidea, Sapygidae). (American Museum novitates, no. 3644)

Abstract: Abstract This study describes the nesting biology of the Egyptian cleptoparasitic wasp Sapyga luteomaculata Pic, which attacks the nests of two species of bees, Osmia submicans Morawitz and Megachile minutissima Radoszkowski, both belonging to the Megachilidae. We include descriptions of the egg/mature oocyte and of the first and last larval instars. We also identify the anatomical changes in the larva that take place as it transforms through intermediate instars from a host-killing first instar to a form adapted to feeding on the stored provisions supplied by the host. Biological subjects treated are egg deposition, ovariole statistics, eclosion, larval behavior including cocoon construction and defecation, and competition with other cleptoparasites. Comparisons are made throughout with accounts of other Sapyginae. Many biological and larval anatomical similarities between Sapyga and cleptoparasitic bees are recognized, and only a few possible cleptoparasitic novelties are identified.

New records of Pseudomasaris Ashmead (Hymenoptera: Vespoidea, Masaridae), with notes on P. phaceliae Rohwer and P. cazieri R. M. Bohart

Abstract: Synopsis New records are given of nine species of Pseudomasaris, and a revised key to species is included. The hitherto unknown female of P. cazieri, and the characters separating P. texanus and P. phaceliae, are described.
